What I know is that Mod won't do things related to stickmen because the game isn't about them :(
did you make the mod? if not ask the same question to the maker of that mod.
Stickman is not the main point of the game.The devs said it themselves.IIRC,the rocket boots were actually fairly hard to add.
Stop whining about the devs not adding what you want.Learn Lua so you can make scripts that fix or add what you want or learn C++ and how to use Github and add the wanted changes and additions to the TPT source code.
